for the 3-cube is rotations of a 2-polytope (square) in 2-space = 4; for the 2-cube is rotations of a 1-polytope in 1-space = 1; In other words, the 2D puzzle cannot be scrambled at all if the same restrictions are placed on the moves as for the real 3D puzzle. The moves actually given to the 2D Magic Cube are the operations of reflection.
Mechanically identical to the standard 3×3×3 cube, but with specially printed stickers for displaying the date. Much easier to solve since five of the six faces are ignored. Ideal produced a commercial version during the initial cube craze. Sticker sets are also available for converting a normal cube into a calendar. Commercial Name: Magic Cube
An example of a 3 × 3 × 3 magic cube. In this example, no slice is a magic square. In this case, the cube is classed as a simple magic cube.. In mathematics, a magic cube is the 3-dimensional equivalent of a magic square, that is, a collection of integers arranged in an n × n × n pattern such that the sums of the numbers on each row, on each column, on each pillar and on each of the four ...
Rubik applied for a patent in Hungary for his "Magic Cube" (Hungarian: bűvös kocka) on 30 January 1975, [4] and HU170062 was granted later that year. The first test batches of the Magic Cube were produced in late 1977 and released in toy shops in Budapest. Magic Cube was held together with interlocking plastic pieces that prevented the puzzle ...
An example of a 3 × 3 × 3 simple magic cube. A simple magic cube is the lowest of six basic classes of magic cubes. These classes are based on extra features required. The simple magic cube requires only the basic features a cube requires to be magic. Namely, all lines parallel to the faces, and all 4 space diagonals sum correctly.
In 1987, Rubik's Magic: Master Edition was published by Matchbox; it consisted of 12 silver tiles arranged in a 2 × 6 rectangle, showing 5 interlinked rings that had to be unlinked by transforming the puzzle into a shape reminiscent of a W. Around the same time, Matchbox also produced Rubik's Magic Create the Cube, [2] a "Level Two" version of ...
A scrambled Rubik's Cube. An algorithm to determine the minimum number of moves to solve Rubik's Cube was published in 1997 by Richard Korf. [10] While it had been known since 1995 that 20 was a lower bound on the number of moves for the solution in the worst case, Tom Rokicki proved in 2010 that no configuration requires more than 20 moves.

The smallest normal pantriagonal magic cube is order 4; see Pantriagonal magic cube. Minimum correct summations required = 7m 2. All pan-r-agonals sum correctly for r = 1 and 3. PantriagDiag: A cube of this class was first constructed in late 2004 by Mitsutoshi Nakamura. This cube is a combination pantriagonal magic cube and diagonal magic cube.
